Contao version 2.11.7 is available. The bugfix release fixes a couple of bugs, including problems when sending e-mails, the missing dependency check when updating multiple extensions at once and the generation of wrong page aliases.
Also, with version 3.0.1 we have removed the automatic copyright notice in the front end according to the announcement of November 8th, 2012 and replaced it with a meta generator tag.
